+- interrupt-names: Should contain a list of interrupt names corresponding to
+ the interrupts in the interrupts property, if available.
+ Valid interrupt names are:
+ - "macirq" (combined signal for various interrupt events)
+ - "eth_wake_irq" (the interrupt to manage the remote wake-up packet detection)
+ - "eth_lpi" (the interrupt that occurs when Tx or Rx enters/exits LPI state)
- phy-mode: See ethernet.txt file in the same directory.
- snps,reset-gpio gpio number for phy reset.
- snps,reset-active-low boolean flag to indicate if phy reset is active low.
